IMPROVEMENT IN SOLE-AND-HEEL BURNISHING MACHINES.

Specification forming part of Letters Patent No. 119,422, datedSeptember 26, 1871-.

Be itv known that I, VIvIAN K. SPEAR, of Lynn, in the county of Essexand State of Massachusetts, have made an invention of a new and use fulMachine for Finishing or Burnishing the Edges of Boot-andShoe H eels;and do hereby declare the following to be a full, clear, and exactdescription thereof, due reference being had to the accompanying drawingmaking part of this specication, and in which- Figure l is a plan, Fig.2, a front View, and Fig. 3, an end elevation of my invention.

I am aware that many machines have been devised for polishing orburnishng the edges of boot-and-shoe heels, and have myself originatedseveral for which Letters Patent of the United States have been allowed.My extensive experience in the practical working of these machines hasconvinced me that the system upon which all now in use operate upon theheel is a wrong one, inasmuch as it tends to loosen or to separate thelifts of a heel and to raise a bur about its tread, since the motion ofthe burnishing-tool, describing a curved path 4about the heel-edge, andthe slope of such heel contracting, as it does, toward its bottom, bothtend to'produce this result. A

My present invention consists, primarily,- in the employment of arevolving wheel or wheels mounted upon a shaft supported in a suitableframe and combined with a carriage or jack for supporting the boot whoseheel is to be operated upon, under such an arrangement that the path ofrevolution of the wheel tends toward the base of the same, or the boot,rather than toward the tread of the heel; by this means avoiding thedanger now prevalent of loosening the lifts of the heel, and producing arough and unfinished edge thereto, as before stated. Secondly, thisinvention consists in an original mode of applying the boot-supportingcarriage or jack to the machine frame by pivoting it thereto in suchmanner that it and the boot may be presented to the action of either thenishing or burnishing-wheel carried by the machine, without thenecessity of employing duplicate jacks and shifting the boot from one tothe other, as is now, of necessity, practiced.

The accompanying drawing represents, at A, the frame of my presentmachine, as composed of a flat plate or base, a, and two curved endstandards or uprights, b b, erected thereupon, such standards serving'to support at their upper extremity a horizontal shaft, c, whichrevolves in suitable bearings carried by such standards. Upon eachextremity of the shaft c, and, by preference, outside of the adjacentstandard b, I mount a circular wheel or disk, d or c, one of suchWheels, viz., d, being composed of soap-stone or other equivalentsubstance, which Will serve to finish or reduce the heel-edge to auniform and smooth surface, while the other disk is of polished steeloran equivalent material, which polishes or burnishes the heel-edgeafter the latter has been subjected to the action of the reducing-wheel.The perimeter of one or both the wheels d or e may be convex, flat, orconcave transversely, but I prefer that such perimeter should be concaveto some extent, in order to cover as great a proportion of the surfaceof the heel-edge as is practicable, by this means producing a better andquicker polish. B in the accompanying drawing denotes a curved bar oryoke, the lower arm of Awhich is mounted and turns loosely upon a stud,

making part of a bracket, which is swiveled to the upper end of anupright post, G, this post being erected in a rigid manner upon theouter extremity of a horizontal vibrating arm or carrier, D, the innerextremity of which is fulcrumed to the base-plate of machine-frame insuch manner that the jack carried by said carrier may be swung from oneto the other of the wheels el e. The yoke B, mounted as explained,constitutes the jack for receiving the boot and presenting its heel-edgeto the action of one of the wheels.

It will be observed that the wheel, revolving in the direction of thearrow thereon, will, if the heel-edge be pressed forcibly in contactwith its periphery, impart a brilliant polish to such edge, and Willtend to solidify and condense such heel.

With a machine organized as herein explained the boot-heel is firstpresented to the action of the reducing disk d, and this operation beingcompleted, is carried about in a circular p ath, with the fulcrum of thecarrier D as a center, and presented to the action of theburnishing-wheel, and this Without the removal or disturbance of theboot.
